The wideband reading is meaningless if it's not running.
Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that?
Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours.
Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
Hello , im new here and i have A31 home build
RB25det neo stock eng / turbo
aem ems 2 blue connector
aem 3.5 map
aem cas disk
aem wideband connected to ecu
355 lph pump
550 nismo yellow injectors side feed
aftermarket regulator
and won’t start with base aem tuner basic tune
eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle
Now it won’t start
Wideband reads 10 and 11 at lowest fuel setting
and will share calibrations soon for aem tuner i think something is wrong in aem tuner
please if you have any information, am very grateful
Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account.
I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit.
They totally have a boost reference from somewhere between the turbo and the throttle(s).
Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads.
**which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
